Adequate sleep is the cornerstone of health. The bedroom environment will affect the quality of sleep to a certain extent. Recently, a study in Nara Medical University in Japan found that the bedroom lights are too bright, which can make the body's biological clock and endocrine disorders, not only affect sleep, but also damage Physical and mental health.
1. Increase the risk of depression. According to the study, any kind of light before going to bed or sleeping, including gaps in the curtains, and the flash of smart phone screens, can disturb the body's biological clock and induce depression. Shanghai Insomnia Medical Collaboration Shi Ming, deputy director of the center, explained that the disturbance of the biological clock can cause insomnia, affect people's mood and affect their behavior. Insomnia or long-term lack of sleep can increase the risk of depression. The data show that 75% of patients with depression have insomnia symptoms. It further deteriorates the condition of patients with depression. The study in the Journal of Behavioral Therapy and Experimental Psychiatry found that people who sleep less than 8 hours a night are more likely to suffer from anxiety and depression.
.2. High blood lipids, obesity, increased risk of heart disease. Shi Ming stated that the quality of sleep affects the body's endocrine system and digestive system. Insufficient sleep or insomnia, the body's endogenous 'lean pheromone' deficiency, unable to feed during the day After the fat is digested, fat builds up, leading to increased blood lipids and increased obesity. At night, the sympathetic tone is less intense than during the day. If the sleep is affected, the sympathetic tone is increased, causing the systolic pressure and diastole of the heart. The abnormal changes in pressure lead to an increased risk of heart, cardiovascular and other diseases.
3. Influencing the production of melatonin and immune factors, more susceptible to cancer. Melatonin is a natural hormone that promotes sleep. According to a study in the journal Physiology Report, exposure to light before going to bed will hinder fading. Melanin secretion, its level directly affects the quality of sleep. Melatonin is the strongest endogenous free radical scavenger found so far. Its powerful antioxidant capacity can effectively prevent cells from oxidative damage. Most of the metabolic or impaired repair processes take place during nighttime sleep. When there is a lack of melatonin secretion in the human body and a lack of immune factors, the quality of sleep will decline, and cell turnover will be impeded, which may lead to canceration.
In general, human sleep can be divided into deep sleep and light sleep. Deep sleep is mainly concentrated in the night from 11 pm to 3-4 am the next morning. After 4 am, deep sleep decreases, mostly light sleep. Physiological activities, such as energy conversion synthesis, hormone secretion, etc., are all done in deep sleep. If the long-term insomnia or poor quality of sleep, it will produce a multi-organ metabolic dysfunction, which will affect the physical and mental health of the human body. Especially children, the quality of sleep It is directly related to growth hormone and memory capacity. 'Shi Ming reminded that in order to have a high quality of life, it is necessary to maintain regular routines, not to stay up late, try to turn off or turn the mobile phone into a flight mode before going to bed; Curtains, to minimize the bedroom light. ▲
